I am a science teacher at Streamwood High School in Streamwood, Illinois. This semester my physical science students tested and compared soil mediums of a 50-50 mixture of potting soil and vermicompost to 100% potting soil. We achieved a 20 to 30 percent increase in the growth rate of plants in the soil medium with the 50-50 mixture compared to the potting soil. The third test we did was to grow plants in a 100% vermicompost medium. Again, these plants did not grow as well as the plants grown in the soil mixture.

Thanks for the feedback. I will have mystudents do more experimentation on the composition of soil and its effect upon the growth of plants. We already tested a 50-50 mixture( garden soil-vermicompost) and compared it to garden soil only.

If we could micromanage the soil and create a more finely tuned compostion and get better results, then that is what we will do!
